When a player hits a football, it moves along the curved path (parabolic path) and then falls to the ground What is the work done by the force of gravity on the football ?

When a ball is moving on plain ground, the work done by the frictional force on the ball is

An object thrown at a certain angle to the ground moves in a curved path and falls back to the ground. The initial and the final points of the path object lie on the same horizontal line. What is the work done by the force of gravity on the object ?
